Vulnerability Details

CVEID: CVE-2016-4560

DESCRIPTION: Flexera InstallAnywhere could allow a remote attacker to execute
arbitrary code on the system. The application does not directly specify the 
fully qualified path to a dynamic-linked library when running on Microsoft 
Windows. By persuading a victim to open a specially-crafted file from a WebDAV
or SMB share using a vulnerable application, a remote attacker could exploit 
this vulnerability via a specially-crafted library to execute arbitrary code 
on the system.
